摘要: A safety attachment for application to the center sill and truck bolster of a railroad car for automatically applying the air brakes of the trainline in emergency, automatically when a car wheel becomes derailed. One such safety device is associated with each car truck, and each such device includes a valve supported by the center sill and having a pivotally mounted lever arm disposed between two fixed arms or furcations supported by the truck bolster, so that one of said furcations will strike and move the lever arm sufficiently to open the valve when the truck bolster is subjected to a leverage force of the magnitude resulting from the derailment of a wheel of the truck of which the bolster forms a part.
